Trait ritual_common::utils::MapIfOk

pub trait MapIfOk<A> {
    fn map_if_ok<B, E, F: FnMut(A) -> Result<B, E>>(
        self, 
        f: F
    ) -> Result<Vec<B>, E>;

Required methods

fn map_if_ok<B, E, F: FnMut(A) -> Result<B, E>>(self, f: F) -> Result<Vec<B>, E>

Call closure f on each element of the collection and return Vec of values returned by the closure. If closure returns Err at some iteration, return that Err instead.
